Vim li cas tus neeg hais lus dia dolphragm yog ib qho tseem ceeb ntawm cov suab sib deev
Tus hais lus diaphragm ua haujlwm ua tusAcoustic Lub PlawvNtawm lub system . nws cov nyom los ntawm multidimensional kev cuam tshuam hauv electro-mechano-acoustic hloov dua siab tshiab:
Kuv {. Tus trilemma ntawm cov khoom siv mechanics
Diaphragms yuav tsum daws peb qhov kev tsis sib haum xeeb lub cev:
| Qhov toob kas | Cuab yeej | Tsis sib haum |
|---|---|---|
| High-zaus teb | Ultra-lub teeb hluav taws xob (tsawg dua los yog sib npaug rau 0.5g) | Txo qis rigidity → breakup distortion |
| Tsawg-zaus tswj | High stiffness (Young's modulus >15GPA) | Nce ntau heev → qeeb kev teb qeeb |
| Midrange Nightness | Kev Zoo Tshaj Plaws Damping (Poob Factor 0.1-0.3) | Txo rhiab / nthuav dav |
Kawm Txog Cov Ntaub Ntawv:
Carbon Fiber: HAND Stiffness tab sis tsis zoo damping → steelic nruab nrab (yuav tsum muaj cov txheej txheem resin tshwj xeeb)
NTAWV NTAWV PAFP: Zoo heev damping tab sis hygroscopic → monsana txheej rau cov av noo tsis kam
